Abstract

A lady bird beetle, Menochilus sexmaculatus Fab. (Coleoptera:Coccinellidae) is biocontrol agent of several homopterous insect pests. Therefore, karyological investigations were carried out in adult male of M. sexmaculatus. The diploid number of 12 chromosomes was depicted by the spermatogonial metaphase. The karyotypes comprised of 10 pair of autosomes and X and Y sex chromosomes.

Abstract

The longevity of ovipositing females of Apanteles jayanagarensis Bhatnagar, a larval parasitoid of Spilosoma obliqua (Wlk.) ranged from 5 to 8 days (X 6.8). The number of progeny produced ranged from 108 to 134 Individuals (X 119.6). The male:female offsprings ranged from 1:0.95 to 1:2.051 (X 1:1.349). The first adult mortality was on the 5th day. The average length of immature stages of parasitoids was 16 days. The maximum mean progeny production per day (mx) was 18.8 on the 2nd day. The intrinsic rate of increase (rm) per female per day was 0.225 and population multiplied 66.71 times in mean generation time of 18.66 days.

Abstract

During first green revolution, use of excess synthetic fertilizers, pesticides and other inputs, adversely affected ecosystems. The second green revolution started as organic farming. Keeping this view in mind, a new eco-friendly vermiwash model has been developed with five main modifications, to get qualitative and quantitative vermiwash. Vermiwash is liquid bio-fertilizer obtained from earthworm activities, i.e., coelomic fluid and vermicasting filtrate.
